Hi! Many thanks for visiting this Sato group webpage at the Neutron Science Laboratory, Institute for Solid State Physics, University of Tokyo! We are working on the dynamical behavior of spins in various systems ranging from the exotic superconductors to the quasicrystalline spin systems. Our primary tool is the neutron scattering.

Spins, which are a quantum mechanical consequence derived in the Dirac equation, behave very interestingly and intriguingly when they interact each other. They sometimes form a macroscopic quantum coherence at low temperatures, or their fluctuations sometimes give rise to superconductivity. The key issue in modern condensed matter physics is indeed the strong electron correlation involving such spins. The neutron scattering is a very unique and powerful tool to investigate such quantum states and fluctuations of spins in condensed matter.

Of course, we need to have high-quality samples to play with. For this purpose, several sample preparation equipments are available at our laboratory, such as the induction-melting, zone-melting and arc-melting furnaces; we are encouraging our group members to prepare/grow samples themselves.

Basic physical properties, such as magnetic susceptibility and electrical resistivity, can also be measured at our laboratory. Much elaborated measurements are done with the collaboration of several other research groups around the world.
